fabric是的一个基于命令行的自动化部署框架,用docker开了两个容器来学习fabric.
#!/usr/bin/env python #-*- coding=utf-8 -*- from fabric.api import * env.hosts=[ 'root@114.215.86.228:22', 'root@114.215.86.228:32', ] env.passwords={ 'root@114.215.86.228:22':'*****', 'root@114.215.86.228:32':'***', } @task def task1(): run('ps') @task def task2(): run('uname -a') @task def dotask(): execute(task1) execute(task2)
执行结果
